UNITED stares PATLEIW? ARTHUR L. RUSSELL, OF HYDE PARK, MASSACHUSETTS, ASSIGNOR T UNITED SHOE MACHINER COMPANY, OF FATERSON, NEW JERSEY, A CORPGRATION OF NEW JERSEY.

To all whom it may concern' Be it known that I, ARTHUR L. RUssnLL, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts. have invented certain IIHPIOVQIYICHtS lH Lasting-Machines, of which the following description, in connection with the accompanying drawings. is a specification, like reference characters on 10,the drawings indicating like parts in the several figures.

This invention relates to lasting machines of the type which Work an upper over-the toe portion of alast by viper plates which .5 are shaped to embrace the end portion of the'last and are closed and advanced to wipe the upper inwardly from the end and opposite sides of the too over the margin of the innersole on the lastbotto'm. In such mas 2O chines the wipers are required to do more or less stretching or pullingv ot' the upper to shape 'itto the toe portion of the last and form it, to the last without wrinkling any portion of the upper that will show in the finished shoe,- Shoes are prepared for the vlastingmachine bythe pulling-over operation in which the upper is seized at the middle of the toe and at the sides of the hall stretched lengthwise of the shoe, and also transversely of the shoe over the ball of the last, and is adjusted into proper relation to thelast. In this preparatory operation the toe tip seam, with which most shoes are now made, is'adjnsted into a desired relation to the last before the upper is fastened. It is important that. this position of the tip seam be not disturbed during the lasting operation. It is the custom of many lasting machine ope 'ators to obtain more e'll'ectivc stretching of the upper about thc toe portion of the last by gripping or clamping the upper down upon the top tare otthe wiper plates by means of a device called a retarder. This device retardsor delays the slipping of the upper over the wipers as the latter and the last are moved relatively and increases t-hc upper-pulling action of the wiper plates. equipped with retarders, while in other in; stances retarders are employed which are Specification of Letters Patent.

the hand of the operator. Aditticulty is, however, frequently experienced in the emvploynient of these retarders because in their use trio upl er the tip seam is drawn forwardly over the top ot the last and curved or bowed This occurs because of the need the operator finds tor strongly pulling the upper at the sides of the toe in order to fit it smoothly to the last and the fact that the upper has already been strongly pulled at the middle of the toe in. the pullii'ig-over operation and cannot be pulled much more without drawing the middle portion of the tip seam' torwardly.

An object of this invention to provide imi' rovcd lasting means by which bowing of tip scams is avoided and the fitting of" the upper to the sides of the toe is facilitated.

To this end important teaturcs of this invention consist. in the provision of a retarder ha v'ing an acting taco which will grip or. clamp theupper against the wiper plates or associated parts with greater force at. the sides ot the toe than at. theend of the toe, and in the combination of a retarder and a subjaeent upper clamping or gripping meniber which are tt'orn'ied relatively to engage and pull the upper at the .end and opposite sides of the too of the shoe and to a greater extent at the sides than at the end of the toe.

The invention will more fully appear from the following description of a preferred embodiment thereof and will be definitely pointed out in the. claims atthe end of the description.

Figure 1 is av perspective view showing, by way of example, lasting means embodying this invention and comprising a retarder and toe lasting plates operatively connected for coopeeitivc use.

'llu: hold down is connected to a lover 22 when the operator observes that the edge of the innersole is being or is liable to be lifted by thostretchingupper that is being pulled up by the wipers and the retardcr. This is particularly liable to occur when the innersole is large and overhangs the edge of the last a trifle. It; is to be noted that the in clination of the hold down and of its path of movemrnt permits its withdrawal from under the upper after'the upper has been wiped over the edge of the inncrsolo past} the position Where the feather is liable to be displaced by it. its I am advised it is new with me to provide in connection with an end lasting mechanism a feather hold down mounted on a support where it is in position to be thrust into holding relation to the innersolo whenever required.

Having described my invention, what claim as new and desire to secure by Letters Patent is:--

7. A retarder comprising two plates pivotally connected together over the middle of the toe for adjustment according to different widths of. shoes and each recessed on its lower faceat and adjacent to said connection to reduce upper gripping pressure at' the middle of the toe over a width varying with the width of shoe for which the plates 'are pivotally adjusted.

8. A retarder comprising a lever pivoted at one end and having a handle at its other end, and an upper clampingmember mounted on the lever and having its lower face formed to clamp the upper at the end and sides of the toe and to hold the upper at the sides with greater security than at the end of the toe.

15. In an end lasting mechanism, a carrier mounted for movement over the shoe and a hold down mounted in the carrier formovement downwardly and forwardly.

16. In an end lasting mechanism the combination with end embracing wipers and supporting and. operating means therefor of a retarder mounted for movement lengthwise of the shoe with the wipers and an innersole tip hold down mounted on the retardcr and arranged for downward and forward movement relatively to the retarder.

17. An apparatus of the class described having, in combination,-toe lasting wipers, a etirder betweemwhieh and the wipers the upper of the endand sides'of the toe is re ceived, said wiper and retarder being relatively recessed in their adjacentfaces be-.

tween which the upper of the'cnd of the toe is received whereby the end of the upper is held less firmly than is the upper at the sides of the toe.

18. an end lasting machine having, in combination, toe embracing wipers and means for operating them, and a retarder comprising manually operable lever to which is attached a crescent-shaped foot having its horns extending toward the rear ofthe shoe and away from the fulcrum of the lever and arranged to permit pressure a pplicd to the lever to'retard slipping of the upper more at the sides than at the end of the toe, the acting face of the body of said footbeing cut away to relieve the pressure at the end of the shoe while maintaining the pressure at the sides of the shoe" 19. An end lasting machine having, in combination, toe embracing wipers and means for operating them, anda retarder comprieing a' manually operable lever to 30 pm; iii 11 and mum;
